I do not find my girlfriend of 4 years attractive anymore. She’s a year older than me.I’m 33 and she’s 34. She became so very toxic and will pick up a fight at every slight opportunity she has. I’m a very loyal boyfriend but recently I met this young girl, she’s 23 and she’s my kid sister best friend. We started dating and we are so much into each other, now I’m confused if I should just move on with my life with the younger girl or stay in my 4 years boring relationship.
